Hi, I'm pretty new to linux so I'm sorry if this is a dumb question, but I really can't find an answer anywhere else, I've been looking for over a week now.
I have an ASUS X556UB laptop, I've formatted the drive to get rid of the windows it came with, and installed Ubuntu Gnome.
However, I'm having trouble getting the machine to use the dedicated graphics card (GTX 940M).
It seems the problem is that I haven't disabled secure boot. The option is greyed out and unselectable in the BIOS, even though I've set admin and user passwords in the security tab.
Can anyone help, should I reformat and start from scratch with another OS? This is the third one I've tried, it's like this laptop is just allergic to linux.
It took me hours and hours to sort all the other problems out, this looks like the last thing. Any help would be greatly appreciated
